A tell-all memoir penned by Meghan Markle, 43, could take the royal feud to “nuclear” as more details about Meghan’s time within the Firm could be revealed, an expert has claimed.

Meghan Markle and her husband Prince Harry stepped down as senior working royals in 2020 and since their move to Montecito, California they have shared intimate details about their private life and relations with the Royal Family in sit-down interviews, and with the release of Harry’s own memoir, Spare.

Speaking to Closer magazine, the source revealed how the couple must be feeling. They said: “It’s not just about pride of hurt feelings, there are very ugly repercussions for them when this constant narrative that they’re family outcasts keeps getting fed. It impacts their brand as well as their morale, and it had the potential to put them more at risk.”

The expert pointed out there is “demand” for Meghan to speak out, adding: “The talk among their friends is that it’s time to take the gloves off and do away with the diplomacy.”

But, the source warned there may not be a positive outcome if another memoir was planned: “Another tell-all would cause so much trouble, this feud would go nuclear.”

The source also claimed that Meghan believed Prince Harry and her not receiving an invitation to Balmoral was a ” personal attack designed to hurt” the Sussexes which could prompt the Duchess to pen her own tome.
